As an example, consider the function h(t), which describes the height of a growing flower at time t. This function is continuous. In fact, a dictum of classical physics states that in nature everything is continuous. By contrast, if M(t) denotes the amount of money in a bank account at time t, then the function jumps whenever money is deposited or withdrawn, so the function M(t) is discontinuous. (However, if one assumes a discrete set as the domain of function M, for instance the set of points of time at 4:00 PM on business days, then M becomes continuous function, as every function whose domain is a discrete subset of reals is.)

**continuous function**(continuity) is a function for which, intuitively, small changes in the input result in small changes in the output. Otherwise, a function is said to be "discontinuous." A**continuous function**with a continuous inverse function is called "bicontinuous."**Continuity**of functions is one of the core concepts of topology, which is treated in full generality below. The introductory portion of this article focuses on the special case where the inputs and outputs of functions are real numbers. In addition, this article discusses the definition for the more general case of functions between two metric spaces. In order theory, especially in domain theory, one considers a notion of**continuity**known as Scott continuity. Other forms of**continuity**do exist but they are not discussed in this article.As an example, consider the function h(t), which describes the height of a growing flower at time t.
